<pre>public class <span class="strong">YUVImage</span>
extends java.lang.Object</pre>
<div class="block">This class encapsulates a YUV planar image and the metadata
 associated with it.  The TurboJPEG API allows both the JPEG compression and
 decompression pipelines to be split into stages:  YUV encode, compress from
 YUV, decompress to YUV, and YUV decode.  A <code>YUVImage</code> instance
 serves as the destination image for YUV encode and decompress-to-YUV
 operations and as the source image for compress-from-YUV and YUV decode
 operations.
 <p>
 Technically, the JPEG format uses the YCbCr colorspace (which technically is
 not a "colorspace" but rather a "color transform"), but per the convention
 of the digital video community, the TurboJPEG API uses "YUV" to refer to an
 image format consisting of Y, Cb, and Cr image planes.
 <p>
 Each plane is simply a 2D array of bytes, each byte representing the value
 of one of the components (Y, Cb, or Cr) at a particular location in the
 image.  The width and height of each plane are determined by the image
 width, height, and level of chrominance subsampling.  The luminance plane
 width is the image width padded to the nearest multiple of the horizontal
 subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of
 4:1:1, 1 in the case of 4:4:4 or grayscale.)  Similarly, the luminance plane
 height is the image height padded to the nearest multiple of the vertical
 subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4
 or grayscale.)  The chrominance plane width is equal to the luminance plane
 width divided by the horizontal subsampling factor, and the chrominance
 plane height is equal to the luminance plane height divided by the vertical
 subsampling factor.
 <p>
 For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is
 used, then the luminance plane would be 36 x 35 bytes, and each of the
 chrominance planes would be 18 x 35 bytes.  If you specify a line padding of
 4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and
 each of the chrominance planes would be 20 x 35 bytes.</div>
